travis has passed 11 tests and his classmate Jennifer has passed 2 tests. Going forward Travis plans to pass 2 tests per week. Meanwhile Jennifer plans to pass 5 tests per week. Eventually she will catch up to Travis. How many tests will each student have passed and how many weeks will it take?

Answers

Answer 1

Answer: If Travis already has passed 11, and Jennifer has already passed 2, then we just add 2 to Travis and 5 to Jennifer x amount of times until they have passed the same amount of tests. So:

Travis:    11 Jennifer: 2
Week1    + 2     + 5
Week2     2    5
Week3     2    5
      -------          --------
17    17

So= it will take 3 weeks for them to have both passed a total of 17 tests each.

For a wall of a given material and of a fixed surface area, the rate of heat loss by conduction through the wall is inversely proportional to the thickness (T) of the wall, and directly proportional to the temperature difference (d) across the wall. The rate of heat loss could be given by which of the following expressions?A. 2d/T
B. 2 T/d
C. 2d + ½ T
D. 2(d + ½ T)
E. T/d

Answers

the answer is A .2d/T
Since d is directly proportional to the heat lost it should be the numerator
since T is inversely proportional to the heat lost it shoudl be the denormirator
that is 1/T ; 2 is the constant
the actual formula is R = kd/T

Order the numbers from least to greatest.-0.5, 3, -3, 1.2
The order of the numbers from least to greatest is (blank)

Answers

The order of the numbers from least to greatest is -3, -0.5, 1.2, 3.

How do we order the numbers from least to greatest?

For us to order the numbers from least to greatest, we first have to arrange the numbers in ascending order based on their values as follows -3, -0.5, 1.2, and 3.

Step 1: Compare -3 with the other numbers because -3 is the smallest, it comes first.

Step 2: We compare -0.5 with the remaining numbers.

Step 3: We evaluate 1.2 in comparison to the remaining numbers.

Step 4: 3, being the largest among the provided values is positioned at the end of the sequence.

Hence, the order of the numbers from least to greatest is -3, -0.5, 1.2, 3.

How many ways are there to select a committee to develop a discrete mathematics course at a school if the committee is to consist of 3 faculty members from the mathematics department and 4 from the computer science department, if there are 9 faculty members of the math department and 11 of the CS department?

Answers

Answer:

There are 27,720 ways to select the committee

Step-by-step explanation:

First, it is necessary to know how many ways are there to select 3 members, if there are 9 members of the mathematics department. This can be found using the following equation:

$nCk=(n!)/(k!(n-k)!)$

Where nCk gives as the number of ways in which we can select k elements from a group of n elements. So, replacing n by 9 and k by 3 members, we get:

$9C3=(9!)/(3!(9-3)!)=84$

So, there are 84 ways to select 3 members from 9 members of the mathematics department.

At the same way, we can calculate that there are 330 ways to select 4 members from the 11 that belong to the Computer science department as:

$11C4=(11!)/(4!(11-4)!)=330$

Finally the total number of ways in which we can form a committee with 3 faculty members from mathematics and 4 from the computer science department is calculated as:

9C3 * 11C4 = 84 * 330 = 27,720

Ninth grade algebra.i am solving for x

Answers

Answer: x = 1

Step-by-step explanation:

So you need to get x completely alone, so take c out of it by subtracting c

-3x = -3 -2c

x = 1 +2/3c

so you would plug that in to solve for C

So you know what x is (or the substitute for it right now)

-3(1 + 2/3c) + 2c = -3

multiply or add

-3 - 2c + 2c = -3

c is 0 when you combine

-3x + 0 = -3

-3x = -3

x = 1

The warehouse of the Alpha DistributionCompany measures 450 feet by 300 feet. If
65% of the floor space is covered, how many square feet are NOT covered?

Answers

Answer:

47,250 ft^2

Step-by-step explanation:

Area: 450 * 300 = 135,000 ft^2
65% of 135,000 =

135,000 * 0.65 = 87,750 ft^2 (space covered)
135,000 - 87,750 = 47,250
